BAIL-ANCHOR.

Specification of Iietters Patent.

Patented May 23, T9116.

Application filed March 6, 1916. Serial No. 82,475.

'Kentucky, have invented certain new and useful Improvements in Rail Anchors, of

which l do declare the following who a full, clear, and exact description, reference being had to the accompanying drawing,

forming a part of this specification.

' The invention consists in the novel features of construction hereinafter described, illustrated in the accompanying drawing and particularly pointed out in the claims at the end of this specification.

Figure 1 is a plan view showing a rail anchor embodying my invention and. showing said anchor applied to-=a railway rail.

Fig. 2 is a side view of-my improved an-' chor, the lower portion of the railway rail being shown invertical section. Fig. 3 is -a view in vertical section on line 33 of Fig. 2, the rail base being omitted. Fig. 4 is an inverted plan view of the locking jaw of my anchor.- Fig.- 5 is a plan view of the end portion of the anchor on which the locking jaw is mounted.

The body portion A of my improved rail anchor is adapted to extend beneath the base of the railway'rail B and bear against the under side ofv said rail base; and at one end the rail anchoris provided with a jaw A preferably formed integral with the body portion and provided with a groove to receive the base flange Z) of the rail. At its opposite end, the body portion A of the rail anchor is depressed or extended downwardly and outwardly and is provided with a depending abutment A adapted to bear against the railway tie G, as shown ,in Fig. 3 of the drawings. On the upper surface of the downwardly and outwardly extended end portion of the rail anchor is formed a raised rib A having an expanded head a, this rib being adapted to. enter a down- -wardly facing groove .2 that is formed in the under side of a lockingaw D, the groove d of this locking jaw corresponding in outline to the shape of the rib A Upon the upper face of the depressed and outwardly extended portion of the rail anchor are formed teeth or serrations a preferably on both sides of the rib A as clearly shown in Fig.

5, although the provisionv of these teeth or serrations a upon both sides of the rib is not essential. So, also, the lower surface of the locking jaw D is formed with teeth or serrations d adapted to engage and in terlock with'the teeth (1 The inner portion of the locking jaw D is provided with a groove d adapted to en' gage the base .fiange b ofthe railB. The rib A is inclined inwardly and downwardly toward the abutment A so that as the looking jaw D is moved toward the abutment and into position for use, it will be caused to securely engage and hold the base flange b of the rail B; and the relative dimensions of'the rib A and the groove in the locking jaw D will be such that as the locking jaw is first applied to the rib, the teeth danger of accidental movement. It will be I noticed that considerable space is formed between the lower inclined face 01' of the locking jaw D and the face a of the body portion A of the anchor, this space allowing a free clearance for dirt,'etc., and inasmuch as the groove in the jaw D faces downwardly, all danger of accumulation of dirt or water in the groove of the locking jaw will be avoided This is a feature of importance, as any accumulation of dirt, cinders, or the like, between the locking jaw" and the anchor would tend, under the con stant ars to which the anchor is subjected,

to wear away the parts and endanger thev loosening of the locking jaw.

The precise details of construction above set out may be varied without departure from the spirit'of the invention.

Having thus described my invention, what I-claim as new and desire to secure by Letters Patent is 1. A rail'anchorcomprising a body portion having at one end a jaw to engage the base flanges of a rail and having at its opposite end a downwardly and outwardly extending portion provided with a raised rib at a distance from its end, and a locking jaw provided upon its under side witha downwardly facing groove to engage said rib and having an outwardly projecting part to bear upon the upper surface of the anchor outside of said rib.

2. A roll anchor comprising a body portion having at one end a aw to engage one of the base flanges of a rail and having at its opposite end a depressed portion pro vided with teeth or serrations and with a raised rib, and a locking jaw provided upon its under side With a groove to engage said rib and with teeth o r serrations to interlock with the teeth or serrations on the anchor.

3. A rail anchor coin-prising a body portion having at one end a aw to engage d. A rail anchor comprising a. body portion. having at one end a jaw to engage one of the base flanges of a rail and having at its opposite end a depressed portion and provided with a raised rib extending transversely of said depressed portion and having an expanded head and a locking jaw provided upon its under side with an eX- I panded groove to receive said rib, said looking jaw being provided upon its inner side with a groove toreeeive the rail flange and with a part extending downwardly from said groove to the depressed part of said body portion.
